[PATCH] D72226: [PM][CGSCC] API for outlined ref edges

I updated this patch such that it can address the underlying problem encountered by the coro-split pass in D71899 <https://reviews.llvm.org/D71899>: we need a method of inserting new ref edges into an existing call graph, whereas currently the `CallGraphUpdater` only allows the insertion of call edges. I don't know if there's any use for such an API in the old CallGraph, so I left that unimplemented. I also considered simply adding this functionality as a member function on `LazyCallGraph` or one of its inner classes, but decided to reuse `CallGraphUpdater` in order to share some of the logic.
